ROBERT E. PEARCE, OF ELMIBA, NEW YORK.

BASIN-TRAP CLEANER AND DRAIN-PIPE-FLUSHING DEVICE.

To all whom it may concern:

Be it known that I, ROBERT H. PEAnoH, a citizen of the United States, residlng at Elmira, in the county of Chemung and State of New ,York, have invented certain new and useful Improvements in Basin-Trap Cleaners and Drain-Pipe-Flushing Devices, of

which the following-is a specification.

This invention relates to certain new -and useful improvements in basin trap cleaner and drain pipe flushing device.

Theprimary object of this invent on is to provide a flushing device for the water outlets of sinks, basins, bathtubs and the like,

and whereby the hydraulic pressure of the water system may be utilized for clearing and cleaning the pipes and the traps con- .well as detached and being adjustablefor accommodating its employment with different sized strainer plates.

In carrying out the functions of this de- I vice, a structure is now designed which is easy and inexpensive to manufacture although possessing requisite strength, the same being also formed of fld]11St2l.ble interchangeable parts. a

With these general ob ects 1n v1ew and others that will appear as the nature of the/ invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim. y

In the drawings forming a part of this application and in which like-designating characters refer to correspondmg parts throughout'the several views: Figure 1 is a transverse sectional View through the device and a ortion of a sink to whichthe same is operat1vely attached, parts being broken away. Fig. 2 is a top plan view of the casing detached. Figs. 3, 4 and 5 are perspective views respectively of the resilient double gasket, one of the securing bolt hooks, and one ofthe combination washers.

Referring more in detail to the drawings,

Specification of Letters Patent.

Application filed April 24, 1915. Serial No. 23,605.

the device is herein illustrated in Fig. 1 as operatively attached to the strainer plate 10 of the sink 11 which plate overlies the outlet pipe 12 of the sink in the usual form of such structures. I

An inverted dish shaped casing 13 formed of cast iron or other desired material has an annular groove 14 in its lower edge 15 and within which groove an annular rubber packing or contact ring 16 is positioned.

Spaced slots 17 are arranged radially through the casing top 18 and in alinement with each other, while a resilient washer strip 19 is adapted for seating upon the casing top and is provided with slots 20 for registering with the casing top slots 17 Bolts 21 are positionable through the said slots 20 and 17 and are provided with angular hooks 22 at their lower ends adapted for hooking engagement through the perforations 23 of the strainer plate as best illustrated in Fig. 1 of the drawings. Rubber washers 24 are arranged upon the bolts 21 overlying the strip slots 20, while metallic washers 25 are superposed thereon, said washers being adhesively secured together, and winged nuts 26 which are threaded upon the bolts are designed for clamping the casing securely to the strainer plate for inclo'sing the same and with the contact ring 16 surrounding all of the perforations. A. section of flexible hose 27 is removably secured to an entrance nozzle 28 which is threaded into the top of thecasing as at 29, a removable clamp 30 being employed for this purpose.

It is to be understood that the hose section 27 is provided of any desired length and has its free end adapted to be removably attached to a usual water service faucet (not shown) and the casing being then secured to the strainer plate 10 and overlying the outlet pipe 12, the faucet is gradually opened which allows the pressure of the water to dislodge and force outwardly any matter or obstructions which may have v positioned, themere turning on of the faucet effects a complete flushing of the drain pipe and a clearing of any trap that may be positioned therein and without the wasting or spilling of any water whatever.

While the form of the invention herein shown and described is what is believed to bethe preferred embodiment thereof, it is nevertheless to be understood that minor changes may be \made without departing from the spirit and scope of the invention as claimed.

What I claim as new.is:-

A device of the class described comprising in combination with a perforated strainer plate, an inverted cup-shaped casing having an annular groove within its lower edge, and spaced radial alining slots in the top thereof, an annular flexible packstrip and casing slots and having the lower 7 ends in hooked engagement with the strainer plate, combination washers and retaining nuts upon the upper ends of the said bolts, an inlet nozzle tapped into the top of the said casing, and a Water supply pipe-removably attached to the said pipe.

In testimony whereof I aflix my signature.
